Rockwell...despite the best intentions of the warnings don't let "too much bike" throw you. If bikes kill people then pencils misspell words, spoons cause obesity and cars make people drive drunk.
You simply need to approach the bike with the understanding that it is unforgiving and use your noodle appropriately. Stupidity kills people, not motos.
Having said that I don't think you will enjoy the 990 as a first bike as much as a more forgiving bike like the GS series or some others because you will have to work too hard (mentally) to ride it and learn at the same time.
And, the KTM is demanding in time and attention so if you're not mechanically inclined be prepared for much higher service costs than average.
It is a highly specialized, high performance bike and those of us who love it are willing to pay the price of owning it, but make no mistake about the expense and time and effort required. This isn't your everyday "dual sport".
Riding should be fun...not work, but the 990 is as safe as any other, actually safer than many with the ABS and great balance...twitchy throttles can be made less twitchy but the service and attention demands never stop.
